FIELD OF THE INVENTION

The present invention relates generally to the field of software development and deployment. More particularly, the present invention relates to a system and a method for tracking and authenticating code transition during one or more phases of software development and deployment.

BACKGROUND OF THE INVENTION

Development and deployment of software applications is progressively becoming complex, fast-paced and critical for success of businesses. Enterprises are required to build, test and deploy new versions of software applications with increasing frequency while maintaining 24×7 operations. To meet the aforementioned requirements of quickly designing, building, testing, deploying, and maintaining software applications, enterprises are adopting Development Operations (or DevOps) practices.

DevOps is a software development method that stresses on communication, collaboration, integration, automation and measurement of cooperation between software developers and other information-technology (IT) professionals.

DevOps acknowledges interdependence of software development, quality assurance, and IT operations, and aims to help an organization to rapidly produce software products and services and to improve reliability and security while providing faster development and deployment cycles. DevOps accomplishes this by facilitating continuous integration and continuous delivery, resulting in faster release lifecycles without compromising on application quality.

Adoption of DevOps practices is relatively high and advanced in certain enterprises like internet, retail, media, and technology. However, for regulated enterprises such as life sciences, healthcare and financial services adoption of DevOps is sporadic and low. Enterprises in the regulated industries often see compliance as the highest priority and mandate, often delaying software delivery automation and DevOps practices. Additionally, software delivery in regulated industries have to comply with a host of regulatory guidelines that makes enterprise automation and DevOps transformation extremely challenging with existing set of tools and technologies. Moreover, implementing DevOps in regulated environment to ensure validation of changes in software code and tracking of changes in said code during various phases of development is a challenging task. Further, providing transparency in the audit trail of one or more events associated with various phases of software delivery is an intricate task. Furthermore, compliance that governs safe, transparent and secure way of holding the system of records for auditing are regulator specific processes.

In light of the above drawbacks, there is a need for a system and a method which can be easily integrated with a DevOps platform and is capable of accelerating software delivery. There is a need for a system and a method which complies with regulatory and audit requirements of enterprises. There is a need for a system and a method where risk-based controls and processes are clearly enforced and recorded in an audit trail. There is a need for a system and a method which is capable of detecting, tracking and authenticating code transition during one or more phases of software development and deployment to appropriate phases of development and deployment. Further, there is a need for a system and a method which is capable of maintaining a tamper resistant, traceable and transparent record of one or more changes occurring during one or more phases of software development and deployment. Yet further, there is also a need for a system and a method which is cost effective and provides superior performance.

FIG. 1 illustrates a block diagram of a system for tracking and authenticating software code transition during one or more phases of software development and deployment in a DevOps platform, in accordance with various embodiments of the present invention.

Referring to FIG. 1, in an embodiment of the present invention, the system 100 comprises a DevOps platform 102, an application delivery management subsystem 104 and a terminal device 106.

In various embodiments of the present invention, the DevOps platform 102 comprises a plurality of tools which are integrated to each other to complete one or more phases of software development and deployment. Each tool in the DevOps platform 102 is associated with one or more phases of software development and deployment. The phrase software development and deployment is representative of software code buildup and software code transition as built artifacts through one or more tools of the DevOps platform 102.

In various exemplary embodiments of the present invention, the terminal device 106 may include but is not limited to a smart phone, a computer, a tablet, a microcomputer or any other wired or wireless processing device. In an embodiment of the present invention, the terminal device 106 may be configured to interact with the application delivery management subsystem 104 to create one or more code authentication elements within a distributed ledger, modify policies defined within respective code authentication elements, map a code authentication element to be executed on occurrence of a particular event type in respective tools of the DevOps platform, detect and analyze code transition during one or more events associated with one or more tools of the DevOps platform 102.

In an exemplary embodiment of the present invention, as shown in FIG. 1, the application delivery management subsystem 104 interfaces with the DevOps platform 102 and a terminal device 106. The application delivery management subsystem 104 retrieves information associated with occurrence of an event in one or more tools of DevOps platform 102, respectively via a queuing channel 108 a. The application delivery management subsystem 104 analyses, processes, parses and extracts data from the retrieved information, executes associated code authentication elements, performs authentication, stores authentication results and outputs the results to the terminal device 106. The application delivery management subsystem 104 interfaces with the terminal device 106 over a communication channel 108 a. Further, the communication channel 108 may include a physical transmission medium, such as, a wire, or a logical connection over a multiplexed medium, such as, a radio channel in telecommunications and computer networking. The examples of radio channel in telecommunications and computer networking may include, but are not limited to a Local Area Network (LAN), a Metropolitan Area Network (MAN), and a Wide Area Network (WAN).

Further, the application delivery management subsystem 104 comprises an application delivery engine 110, a processor 112 and a memory 114. The application delivery engine 110 is configured to automatically retrieve, extract and analyze complex event data, create and manage code authentication elements, authenticate software code transition, and maintain a record of each event and state change in a distributed ledger.

In various embodiments of the present invention, the application delivery engine 110 is configured to create one or more code authentication elements within a distributed ledger. Each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of DevOps platform 102 after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication. In an exemplary embodiment of the present invention, each code authentication element may be implemented as a smart contract. The code authentication element may be deployed as chain code within the distributed ledger. In an embodiment of the present invention, the distributed ledger is a blockchain ledger. In an exemplary embodiment of the present invention, a standard distributed open source ledger for instance, Hyperledger Fabric is integrated with the application delivery engine 110. In various embodiments of the present invention, the application delivery management subsystem 104 may be implemented with any distributed and decentralized ledger.

The application delivery engine 110 maps respective code authentication elements with one or more event types occurring in respective one or more tools of the DevOps platform 102. In an exemplary embodiment of the present invention, each policy within respective code authentication element is mapped with an event type. As already described in paragraph 25, each policy is representative of a set of conditions which should be attained for successful authentication of the software code build up during an event type. A code authentication element is executed on occurrence of the one or more event types. A policy within a code authentication element is executed to authenticate corresponding event type. In an example, the event types are code check-in and clear review of code check-in in the tool SCM 102 b of the DevOps platform. The two event types are mapped with a code authentication element. The code authentication element comprises one or more policies, where a first policy includes a first set of conditions to authenticate code check-in and a second policy includes a second set of conditions to authenticate clear review of code check-in. The code authentication element defines the entry and exit criteria between one or more tools of the DevOps platform 102. The one or more code authentication elements ensure that the software code built up in one tool of DevOps platform 102 transitions to appropriate tool of said platform 102 only if the conditions specified within the respective policy of the respective code authentication elements are satisfied. An example of the policy defined within the code authentication element may include, but is not limited to continuous integration tool (102 c) triggers deployment only if result of static code analysis tool (102 d) and code coverage percentage are above the threshold values defined within the policy. The application delivery engine 110, maintains a database of one or more code authentication elements mapped with corresponding one or more event types in a local data storage (not shown) hereinafter referred to as event-contract database.

Further, the application delivery engine 110 facilitates the modification of one or more policies defined within respective code authentication elements via the terminal device 106. In an exemplary embodiment of the present invention, the created code authentication elements can be edited or deleted by one or more developers via the terminal device 106. In an exemplary embodiment of the present invention, the code authentication element is a smart contract, deployed as chain code within the distributed ledger.

In another exemplary embodiment of the present invention, a developer may define, edit and delete code authentication elements by accessing the application delivery engine 110 via a terminal device 106 through a web portal.

Further, the application delivery engine 110, retrieves information associated with occurrence of an event in one or more tools of the DevOps platform 102, respectively via a queuing channel 108 a. The examples of the queuing channel may include but are not limited to message queue tools such as RabbitMQ. The retrieved information is parsed to extract data including but not limited to event type, event time, user initiating the event, associated tool where event is initiated etc.

The application delivery engine 110 determines the code authentication element to be invoked from the event-contract database (as already described in paragraph 26) based on the identified event type. As already described in para 25, each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of DevOps platform 102 after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication of the software code built up during the event type. The invoked code authentication element performs the authentication process on the software code under development during occurrence of the identified event type to validate code transition to subsequent tool of DevOps platform based on the policy associated with the event type. The application delivery engine 110 determines if the result of the authentication process is inline with a policy defined within the code authentication element. If the result is inline with the defined policy then the software code transition to the subsequent tool is authorized and the code is prepared for transition. If the result of the authentication process is not inline with the policy defined within the code authentication element, the code transition is prevented and a notification is sent to the terminal device 106. As already explained above, the code transition from one tool of the DevOps platform 102 to another tool is representative of a state change.

Each tool in DevOps platform 102 is associated with one or more phases of software development and deployment, thereby the one or more code authentication elements ensure that a phase of software development and deployment does not proceed to subsequent phase until the set of conditions defined in the corresponding policy are attained. Example of the set of conditions defined within the policy may include, but is not limited to code commit is allowed if two or more people vote for code commit. Other instances such as CI integration to not skip code quality checks, code coverage target has to be met etc. may be enforced using contract policy.

Subsequent, to the authentication process the application delivery engine 110 stores the result of the authentication process in the distributed ledger. The stored results are available for querying and auditing purposes in future. In an embodiment of the present invention, the application delivery engine 110 comprises a tracking and auditing unit 110 a. The tracking and auditing unit 110 a, audits and tracks authentication results and state changes stored in the blockchain ledger. In an exemplary embodiment of the present invention, the tracking and auditing unit 110 a, may perform auditing and tracking based on one or more parameters. In an exemplary embodiment of the present invention, the one or more parameters may include, but are not limited to time period i.e. start date and end date, event type, DevOps tool name or phase of software development and deployment, and artifacts such as Change Requests, User stories, Defects listed alongside DevOps tools. The tracking and auditing unit 110 a may perform a detailed search of each of the phase or event to trace the related events to view associated metadata like user who triggered it, time stamp, etc. in response to auditor queries received via the terminal device 206. The audit-results are displayed on the terminal device 106.

In another embodiment of the present invention, the application delivery management subsystem 104 may be implemented in a cloud computing architecture in which data, applications, services, and other resources are stored and delivered through shared data-centers. In an exemplary embodiment of the present invention, the functionalities of the application delivery management subsystem 104 are delivered to the terminal device 106 as software as a service (SAAS) over the communication network 108 b.

In another embodiment of the present invention, the application delivery management subsystem 104 may be implemented as a client-server architecture, wherein the terminal device 106 accesses a server hosting the subsystem 104 over a communication network 108 b.

In yet another embodiment of the present invention the application delivery management subsystem 104 may be accessed through a web address via the terminal device 106.

FIG. 2 is a detailed block diagram of a system for tracking and authenticating software code transition during one or more phases of software development and deployment in a DevOps platform, in accordance with various embodiments of the present invention. The application delivery management subsystem 202 interfaces with the DevOps platform 204 to retrieve information associated with occurrence of one or more events in one or more tools of the DevOps platform 204. The application delivery management subsystem 202 analyses, processes, parses and extracts data from the retrieved information, executes associated code authentication elements, performs authentication, stores authentication results and outputs the results to a terminal device 206. The application delivery management subsystem 204 comprises an application delivery engine 208, a processor 210 and a memory 212.

In various embodiments of the present invention, the application delivery engine 208 has multiple units which work in conjunction with each other for tracking and authenticating code transition during one or more phases of software development and deployment in the DevOps platform 204. The various units of the application delivery engine 208 are operated via the processor 210 specifically programmed to execute instructions stored in the memory 212 for executing respective functionalities of the units of the subsystem 202 in accordance with various embodiments of the present invention.

In an embodiment of the present invention, the application delivery engine 208 comprises an element generation unit 214, a local data storage 214 a, a distributed ledger 216, a data collection unit 218, an event interpretation unit 220, a enforcement unit 222 and a tracking and auditing unit 224.

The element generation unit 214 is configured to create one or more code authentication elements within the distributed ledger 216. Each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of DevOps platform 204 after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication. In an exemplary embodiment of the present invention, each code authentication element is deployed as chain code within the distributed ledger 216. In an embodiment of the present invention, the distributed ledger 216 is a blockchain ledger. In an exemplary embodiment of the present invention, a standard distributed open source ledger for instance, Hyperledger Fabric is integrated with the application delivery engine 208. In various embodiments of the present invention, the application delivery management subsystem 202 may be implemented with any distributed and decentralized ledger.

Further, the element generation unit 214 maps respective code authentication elements with one or more event types occurring in respective one or more tools of the DevOps platform 204. In an exemplary embodiment of the present invention, each policy within respective code authentication element is mapped with an event type. As already described in paragraph 25, each policy is representative of a set of conditions which should be attained for successful authentication of the software code build up during an event type. A code authentication element is executed on occurrence of the one or more event types. A policy within a code authentication element is executed to authenticate corresponding event type. For instance the event types are code check-in and clear review of code check-in in a SCM tool of the DevOps platform 204. The two event types are mapped with a code authentication element. The code authentication element comprises one or more policies, where a first policy includes a first set of conditions to authenticate code check-in and a second policy includes a second set of conditions to authenticate clear review of code check-in. The code authentication element defines the entry and exit criteria between one or more tools of the DevOps platform 204. The one or more code authentication elements ensure that the software code being developed transitions to subsequent tool only if the conditions specified within the respective policy of the respective code authentication elements are satisfied. An example of the policy defined within the code authentication element may include, but is not limited to continuous integration tool (102 c FIG. 1a ) triggers deployment only if result of static code analysis tool (102 d FIG. 1a ) and code coverage percentage are above the threshold values defined within the policy. The element generation unit 214, maintains a database of one or more code authentication elements mapped with corresponding one or more event types in the local data storage (214 a) hereinafter referred to as event-contract database.

Further, the element generation unit 214 facilitates the modification of one or more policies defined within respective code authentication elements via the terminal device 206. In an exemplary embodiment of the present invention, the created code authentication elements can be edited or deleted by one or more developers via the terminal device 206. In an exemplary embodiment of the present invention, the code authentication elements are deployed as chain code within the distributed ledger 216.

In an embodiment of the present invention, the data collection unit 218, retrieves information associated with occurrence of an event in one or more tools of the DevOps platform 204, respectively via a queuing channel 108 a of FIG. 1. The examples of the queuing channel may include but are not limited to message queue tools such as RabbitMQ. The data collection unit 218 parses the retrieved information to extract data such as event type, event time, user initiating the event, associated tool where event is initiated etc.

The event interpretation unit 220 is configured to receive the parsed information from the data collection unit 218. The event interpretation unit 220 determines the code authentication element to be invoked from the event-contract database maintained in the local data storage 214 a based on the identified event type. As already described above in para 37, each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of DevOps platform 204 after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication of the software code build up during the event type.

The enforcement unit 222 is configured to receive the code authentication element information as determined by the event interpretation unit 220. The enforcement unit 222 invokes the code authentication element and enforces policies defined within the code authentication element. The invoked code authentication element performs the authentication process on the software code under development during occurrence of the identified event type to validate code transition to subsequent tool of DevOps platform 204 based on the policy associated with the event type. The enforcement unit 222 determines if the result of the authentication process is inline with a policy defined within the code authentication element. If the result is inline with the defined policy then the software code transition to the subsequent tool is authorized and the code is prepared for transition. If the result of the authentication process is not inline with the policy defined within the code authentication element, the code transition is prevented and a notification is sent to the terminal device 206. As already explained above, the code transition from one tool of the DevOps platform 204 to another tool is representative of a state change.

The enforcement unit 222 is configured to ensure that a phase of software delivery and deployment does not proceed to subsequent phase until the set of conditions defined in the corresponding policy of the invoked code authentication element are attained. Example of the set of conditions defined within the policy may include, but is not limited to code commit is allowed if two or more people vote for code commit. Other instances such as CI integration should not skip code quality checks, code coverage target has to be met etc. may be enforced using contract policy.

Subsequent, to the authentication process the enforcement unit 222 stores the result of the authentication process in the distributed ledger 216. The stored results are available for querying and auditing purposes by the tracking and auditing unit 224.

The tracking and auditing unit 224 is configured to audit and track authentication results and state changes associated with code transition stored in the distributed ledger 216. In an embodiment of the present invention, the tracking and auditing unit 224, may perform auditing and tracking based on one or more parameters. The one or more parameters may include, but are not limited to time period i.e. start date and end date, event type, DevOps tool name or phase of software development and deployment, and artifacts such as Change Requests, User stories, Defects listed alongside DevOps tools. The tracking and auditing unit 224 can perform a detailed search of each of the phase or event to trace the related events to view associated metadata like user who triggered it, time stamp, etc. in response to auditor queries received via the terminal device 206. The audit-results are displayed on the terminal device 206. An example of the audit results is shown in table 2 below:

FIG. 3 is a flowchart illustrating a method for tracking and authenticating software code transition during one or more phases of software development and deployment in a DevOps platform, in accordance with various embodiments of the present invention.

At step 302, one or more code authentication elements are created within a distributed ledger. In an embodiment of the present invention, each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of DevOps platform 102 after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication of software code build up during an event type. In an exemplary embodiment of the present invention, each code authentication element is implemented as a smart contract. The code authentication element is deployed as chain code within the distributed ledger. In an embodiment of the present invention, the distributed ledger is a blockchain ledger.

At step 304, a code authentication elements is mapped with one or more event types and stored in a local data storage. In particular, respective code authentication elements are mapped with one or more event types occurring in respective one or more tools of the DevOps platform 102. In an exemplary embodiment of the present invention, each policy within respective code authentication element is mapped with an event type. As already described above, each policy is representative of a set of conditions which should be attained for successful authentication of the software code build up during an event type. A code authentication element is executed on occurrence of the one or more event types. A policy within a code authentication element is executed to authenticate corresponding event type. For instance the event types are code check-in and clear review of code check-in in the tool SCM of the DevOps platform. The two event types are mapped with a code authentication element. The code authentication element comprises one or more policies, where a first policy includes a first set of conditions to authenticate code check-in and a second policy includes a second set of conditions to authenticate clear review of code check-in. The code authentication element defines the entry and exit criteria between one or more tools of the DevOps platform. The one or more code authentication elements ensure that the software code being developed transitions to subsequent tool only if the conditions specified within the respective policy of the respective code authentication elements are satisfied. An example of the policy defined within the code authentication element may include, but is not limited to continuous integration tool triggers deployment only if result of static code analysis tool and code coverage percentage are above the threshold values defined within the policy. A database of one or more code authentication elements mapped with corresponding one or more event types is maintained in a local data storage hereinafter referred to as event-contract database.

At step 306, information associated with occurrence of an event in a tool of DevOps platform is retrieved and parsed. In an embodiment of the present invention, information associated with occurrence of one or more events in one or more tools of the DevOps platform, respectively is retrieved via a queuing channel. The examples of the queuing channel may include but are not limited to message queue tools such as RabbitMQ. The retrieved information is parsed to extract data such as event type, event time, user initiating the event, associated tool where event is initiated etc.

At step 308, code authentication element to be invoked is determined based on the parsed information. In an embodiment of the present invention, the code authentication element to be invoked is determined from the event-contract database maintained in the local data storage based on the identified event type. As already described above, each code authentication element is representative of an authentication process and an action to be executed within corresponding tools of the DevOps platform after the authentication process. Each code authentication element comprises one or more policies, where each policy is representative of a set of conditions which should be attained for successful authentication of the software code build up during the event type.

At step 310, determined code authentication element is invoked. In an embodiment of the present invention, the determined code authentication element is invoked and policies defined within the code authentication element are enforced. The invoked code authentication element performs the authentication process on the software code built up during occurrence of the identified event type to validate code transition from one tool to another appropriate tool of the DevOps platform based on the policy associated with the event type.

At step 312, a check is performed to determine, if the result of the authentication process is inline with a policy defined within the code authentication element. At step 314, if the result of the authentication process is inline with the defined policy then the software code transition to the subsequent tool is authorized and the code is prepared for transition. The state change is stored in the distributed ledger and is available for querying and auditing purposes. As already explained above, the code transition from one tool of the DevOps platform to another tool is representative of state change.

At step 316, if the result of the authentication process is not inline with the policy defined within the code authentication element, the code transition is prevented and a notification is sent to the terminal device. This ensures adherence to one or more policies of DevOps platform.
